Batboard

Hi

I have two batteries here - one aftermarket NTN7143 clone, and one genuine Motorola one.

The Motorola one's cell are worn. Seeing as the cheapass battery's tabs have cracked off, I want to put cells guts into the old Moto battery.

Is there an easy(ish) way to open the Motorola battery without destroying it?

Thanks

Used to open MX300 batteries and replace cells (first job in Melbourne)
We used to use a hack saw and cut along the four lines in the base.
replace the cells, glue the base on and stick it in a vice for 5 minutes.
It worked but was a bit labour intensive.

I would try a hot knife or something similar ( and no not the hot knives seen at RMIT parties although would be fun)
A red hot exacto knife should put a nice slice in the seam.

Good luck

I simply use a thin knife, and a small 'hammer' to drive the edge into the plastic, then lift upwards to separate the case halves.

The top sections of the cases are the biggest hassles as they always appear to be the areas with the largest concentration of adhesive and/or welding(ultrasonic).

If there's corrosion inside, and on the tops of the cells, toss them even if they check good, as they will not last long, and are beginning to leak.

Some cases are somewhat easy to open while others are all but mission impossible, and batteries that have folded, odd shapes like Jedi batteries and GP300/P110 types are always no joy.

MT/MX and such batteries are at least simpler and require less 'plastic assault' than several others require, so a rebuilt battery can retain some of its looks once reassembled.
